TYPEWRITING MACHINE.

Application led January 17, 1924. .Serial No. 686,811.

My invention relates` to collating mechanism tor ty pewriting machines and its chief objectis to provide improved means for collating or assembling work sheets in desired relationship preparatory to writing entriesV in duplicate at varying predetermined positions on the diilerent sheets. Another objcct oit my invention is to provide new and improved paper clamping devices; and still another object is to provide new and im proved paper guiding devices.

To the above and other ends which will `hereinafter appear, my invention consists in the features ot construction, combinations otl devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

In carrying out my invention in the present instance, I provide a bail comprising a cross bar and which is hung or suspended from the platen carriage of the machine, the side arms of the bail being pivoted on the trame of tally` roll mechanism which is mounted on the carriage. The cross bar of the bail is disposed above the platen at its 'front side and provides a support for a pair ot paper controlling or clamping contrivances which are individually settable at diflie/rent' points along the cross bar and lengthwise oi the platen so as to take care of work sheets of dili'erent widths. The paper clamping contrivances comprise each a plate-like kportion on which is pivoted a clamping aw, the clamping jaw carrying an inner side edge guide for a narrow work sheet or bill and the plate-like portion having on it an outer side edge guide for a wider record or ledger sheet. The clamping contrivances are adapted to be opened and closed in concert or simultaneously in all of their adjusted relationships by means comprising a rock shaft supported by the bail and provided with a linger piece, eachcontrivance having` an individual train of connections with the rock shaft, these trains being automatically adjustable along with the contrivances. The construction is such that the linger piecetor controlling the clamps oc cupies a constant or single normal position on its mounting,'while` the clamps may occupy a variety of set positions lengthwise of the platen. The entire mechanism may be 'thrown back vout of the way ore-and-aft of the machine by-turning the bail on its pivots, v

thus ail'ording access to the underlying tally roll mechanism, with which my present in vention is usually associated,as well as affording a ready means of dispensing with the mechanism when it is not to be used.

The present form of the invention may be advantageously employed in connection with two work sheets such as a ledger or record sheet and a statement or bill, which may bey used with' the tally sheet, the three sheets all heilig written on simultaneously by means of transfer sheets or carbons after the statement and ledger sheets have been collated or assembled in desired relationship.

In thus usingv the invention, the clamps are lirst opened together and the 'feed rollers that co-operate with the platen are thrown oil' by the usual release or in some cases 'automatically. The ledger and statement sheets with an interleaved carbon are .inserted together from the yback and moved around under the platen and up at the iront past the printing line and over the cross bar of the bail and the plate-like parts ot the clamps. The clamps having been properly set or spaced apart for the record sheet,the latter will be guided between the liXed side guides on said clamps and in closeproximity thereto, either or both of the guides serving as a side edge gage or gages. The` usual line finder of the machine is employed to gage thefrecord sheet vertically. The record sheet having thus been properly positioned, the clamps are simultaneously thrown on to clamp its side edges above the printingline, thus leaving both hands otl the operator free properly to adjust the bill sheet which may be in the present case aligned lengthwise of the platen against the left-hand side edge guide carrie-d by the clamping jaw', the bill sheet being so narrow as to pass inside the clamping jaws. The vertical alignment of the bill sheet is effected by the regular line nder. The invention will be describedy in detail and explained more at length in connection with the accompanying drawings wherein Figure l is a perspective view of the preferred form of my-invention.

As'appears troni llig. 2, the top plate l or open training ot the lleinington typewriting machine, to which the present forni of in'y invention is shown as applied7 is provided with posts or lugs 2 and to which are secured lined grooved guide rails el and 5, said rails co-oijierating through anti-triction rollers G with the trent and rear grooved bars 'i' and 8 of a` rectangular carriage truck that Afurther coinprises end bars 9. Supported on the carriage truck is a platen 'traine or carrier comprising` end bars 10 on which is joiirnaled a` cylindrical or roller platen 11. llo-operative with the platen, are the usual paper feeding' devices comprising' inain and secoi dary rollers7 conventionally illustrated and numbered respectively 12 and 13, these teed rollers norinally cooperating with the platen to advance thepapei' thereover when the platen is turned. Said feed rollers are adapted to be thrown off or released by releasing devices comprising' a roel; sha` lil which extends lroin side to side of the platen traine and is supported in the end bars 10, said sli-i i. being; provided near its left-hand end with a lease liey comprising an upstafiding; cranlr arni 15 terminating in a linger pieve or key 18. 'llie throw-ofi" or released position ot the feed rollers 12 and 13 is illustrated by dotted lines in The platen may be turned tor liecing the paper by the Vusual line spacing' devices or iigjcr wheels, 'not shown herein, the line spacing' handle beine' effective not only to turn the platen tlii'oiifgh line space distances, but also when siitliciently pressed to restore the platen ,and platen carriage eon'iprisiiig the platen ne and the truck frein lett to right to position the platen .tor beginning' a new line ot ing', the iifi'itiiig' being' en l with the usual ribbon and type bai' mecha.

The arras 18 in the present ease are soinewhat longer than those disclosed in the aforesaid application oit l-lar f. These angular brackets are connected by tie rods 19 and 20, making a supporting' frame which is mounted on the carriaeje, the

'lhe 4bail E28, 3G se ves as a: support for a phirality oit individual paper controlling or collatingl contrivances `which are adjustaloly mounted independently of each other on the cross bar 230. llach contrivance, designated as a whole by the numeral 37, comprises a plate-likeor tabular. support ltor paper, a paper elainp and two paper guides or gages which are alternatively disposed tor use.

Each plate-like part 38 terminates at its upper end in. a rearwardly curved or hoodlike portion` 39,1the lower .end ot the plate being bent rearward as indicated at 40. The outer` end ol each plate is angularly bent forward at right angles to the body portion, providingan ear 4l. Projecting Yfrom the rear tace of each plate are the cone-like heads 42 ot rivets 43. There are two of these ceneri rivets 42, .43 spaced apart on v'each plate so that the heads 42 may engage with the upper edge portion of the supportingrbar 3l), this edge ot the bar being beveled to co-opc" te with the coned heads. The lower edge et the bar 30 is oppositely beveled andis engaged by a wedge, clamp or plate which is secured against the back ot the plate Btl by a screw 45. Lugs 46 struck rearward troni the body ot the plate 38 provide seatsl tor theplate at its `lower side and prevent it :troni turning 01' being displaced. Vbe impor or beveled edge or the plate 4 4 lli; the bevel at the bottom ot the `bar 30, and

whenlthe screw4`is tightened it wedges the Cit bar p under the coned rivet heads 42, thus er clamping the plate 38 and i the whole contrivance 87 in fixed position on the bar 80. Byloosening the screw the contrivance is treed so that it may be slid'along the bar 30 and adjusted in ai'iy desired position after which yit niay be setcr lined by tightening the screw 45. 'lhe plate 38 not only receives and supports the paper when it is ted upward from the platt-n but also constitutes a support tor the other parts oit the contrivance 37. Secured to the outer tace of each ear 4l by rivets 47 is :i bracket comprising an uprightportion Sprovided with parallel outwardly extend` ing` ear portions 49. These ear portions are perforated to provide bearing openings for an upright rod or rock shatt() which serves as a support tor a clan'iping member or jaw. Said ineniber comprises a curved crank or arni 5l provided with a hub portion 52 fit- `.tingvover the associate rockshaft 50 and l pinned thereto between its ends .at 53. A'

crank arni curves forward and inward around both the bracket part 48 and the ear 4l andin .iront ot the associate plate 38 terminates in a downwardly bent ear 54. rllhis guide 59 that is disposed at right-angles to the face of the plate 38 and is adapted to contact with said plate along` its rear edge,

said side guide covering both thev associate ear 5S and the clampingarm 56. It will be understood that the side guides 59 ot the two eontrivances 37 project inward towards each other, the two constituting inner side guides or for the narrow work sheet or bill. j'

Outer side guides or gages for a wider sheet, such as a record or journal sheet, are constituted by tint pieces or plates 60, one for each contrivance 37. Each plate 60 is secured to the inner tace ot the associate ear 4l by screws Gl and projects outward at richt-angles troni the associate plate 3&5 with w rich it is held in unvaried rigid relationship by the screws (51. is appears from ir" l r. f. laid 2, the lower end portionsl ot the outer guides or gage plates G0 extend downward towards the platen below the plates or supports S8 and terminate somewhat above the printing line. The plates or gages G0 are so related to the platen that as the wider work sheets advance upward past the'printing line they are almost immediately brought within the control. ot said side guides G0. lt will be` understood that the relationslnp between the side guides 6G may be varied by readjusting the contrivances 37 `bringing the side Aguides closer together or spacing theni further apart accordingas the eontri'winces are inoved inward or outward. This likewise applies to the inner guides 59 which are also supported on the contrivances 37. During such readjustnient ot the contrivances, the relationship et the. inner guide 59 and its companion outer guide t3()Y on each contrivance is not altered. However, the mounting ot the guide 59 atlords ii'reans for 'varying the relationship letween itand its sociate or companion guide d() without disturbing the :iet position ot the contrivance 37 on which they are supported. rlfhus by' loosening the two screws and 57, the arm 5G .fmayibe swung inward on the screw 55 as a pivot to the lposition for example illustrated llc fit)

`when said eontrivanees are adjusted along their common support 30, said connecting* trains may he automatically.adjusted at the saine time andl yet he always adapted to transmit angles thereto. In the present instance, the aforesaid means comprises clips 78 which at their inner ends are secured hy rivets 7 9 to the .tops ofthe hood-like portions on 'the plates 33. Said clips 73 extend outward over the tops ofthe huhs 74e and crank arms 73, heine" hent upward to provide off-.sets 78 so as not frictionally to engage with said crank arms and hubs. The outer` ends of said clips are hent downward as indicated at 80 outside the crank arms 73. The construction is such that the crank arms 73 and their hulos are loosely conlined between the clip ends 80 and the hood-like portions 39 of theplates 38, so that while the rotary movements of the crank arms with the rock shaft 70 are not interfered with` said crank arms will nevertheless he compelled to nieve slidA alol-y on the rock shaft when the associate contrivanees are moved alone' their support 30. The clip ends 8O will. force the crank 73 to move inward; while the hoods 39 will en- `rage the cranks whenthe contrivances 37 are pressed apart and will force the cranks and the connected ends of the links 77 to slide and move outward away from each other.

it will. he understood that the position of the 'linger piece 72 will remain constant or unchanged for all of the adjusted positions of the contrivances 37 and their trains of connections; and that hy turning the linger piece in the direction `of the arrow in the springs 65 will he overcome and the clamps opened.y while a reverse turning;n permits the clamps to close. Thus the turning` of the finger piece in thedirection indicated likewise rotates the rock shaft 70 and swings the crank arms 73 from the front or Fig. i position backward to the Fin: 4 position. This movement of the crank arms pulls the links 77 rearward and turns 'the crank arms G4- from the front outward. such movement heini; transmitted through the shafts o() to the crank arms 51 and the clamps and guides carried hy said. cran^` arms, the clamps heine; thus simultaneously opened or swung movement from i the horizontal" shaft 70 to the two vertical shafts 5() at right outward from the Fig. 3 to the Fig. 4t p0sition. rihe latter part of the `movement is assisted the clamp springs. Comparing the relations of theparts in F igs. 3 and 4, it will lie observed that the effect of the springs (l5 as transmitted through the links 7 7 is in one case to hold the clamps closed awainst the ce-operating` parts 38 and in the .ase to hold the clamps open, the limit of movement heine determined hy the eX- treme 1mickward limit to which the crank arms 73 can he pushed hy the links 77 under the impulse of the springs, as in Fig. 4:. ln other words, the clamp. springs are douhle actingserving' to hold the clamps closed and also to hold them open. In order simultaneously to close the clamps from their open or irl-operative position, Fig. 4f, it is only necessary to turn the .finger piece or key 72 oppositely from the direction of the arrow in said figure.

it will he understood that the embodiment of my invention as ahove described is caiahie oi a variety of uses and that parts of the invention may be` used without other parts.

The present construction however A `c1ilar'ly designed and is well adapted .or c .latiner a narrow statement 0r hill sheet and a wider record or ledger sheet. is well understood. the depth of the previeu-1: written matter on the two sheets may rv arcord' 9J to circumstances, so that sucvo pairs of sheets require varying assemhlingg; or collatinn. In .Figure l of the drawinej. the wide or record sheet` is designated zu, thehill sheet or statement is designated as 7) and the transfer or carhon sheet inte-r posed het-Ween the sheets a and t) is designated as c. This carbon sheet c is adapted to o. viinpressions on the underlying record sheet c simultaneously with the printing of l l l :se oill sheet 7). which is effected through the usual ink rihlcon. Let it loe assumed that the clamping); contrivances 37 have been adjusted on their support so thatthe record moet c may pass freely hetween the outer side rundes (i0: and also that the inner side .Quides and more particularly the lefthand one. has heen adjusted relatively to its associate guide 60. so as to leave the proper left-hand margin exposed on the underlying record sheet a. In operation, the clamps are openedv and the main and secondary feed rollers 1Q and 13 are thrown oif or released, as shown hy dotted lines in Fig. Q. The operator then introduces the sheets a, and c together from the rear over the usual paper talile. not shown, passingV the sheets under the platen and up at its forward side. It may ,he stated that the carbon sheet is slightly lill all

troduced under the Ytold, so that the two sheets may be readily handled together.

fis the sheets a, l) and c are advanced at 'trent side oitl the platen under the usual Si, the record sheet a will be ,juid-ed iito substantially the proper positien lengthwise ot the platen by the outer side guides GO between which the side edges of sheet a will just pass. Vertically the record sheet will be positioned by the aid of 'the line gage i8, and said sheet will be advanced or pushed up until the next line to be printed on it registers with the line gage. llo :tacilita'te adjustment in respect to the line gage, a cross mark (Fig. l) or other suitable indicia may be written in the righthand margins on completion ot the last prior entry on the record and bill sheets. litter such adjuS-itment, the linger piece 'T2 is actuated to throw the clamps together on or into engagement with the side edge portions ot the sheet a. above the printing line, said sheet being` held or clamped by the cooperation ot the movable clamping elements 56 with the plate 38. Both hands ot the operator are thus lett 'tree 'for the collating or assembling` of the bill sheet b in proper superposed relationship with the record sheet a. To this end the bill sheet is adjusted lengthwise ot the platen by the aid ot the lettehand side guide 59. As shown in the drawing` the right-hand side guide is spaced rightward so that it does not co-operate with the right-hand edge of the bill sheet. llt will be plain, however, that iit desired, this right-hand guide may also be adjusted to co-operate with the bill sheet. 'llhe bill sheet is'next adjusted in the proper position vertically by the aid ot the line ga 8l. alter which the iteed rollers l2 and i3 are thrown on as by actuating the linger piece or hey 16, the 'feed rollers holding the worlr sheets in collated relationship so that 'the clamps may be simultaneously opened by actuating the linger' piece 72. The writing et the collated sheets may then be proceeded with in the usual way. A 'iter the writing on the sheets completed` they are withdrawn and the above outlined operations repeated with succeeding pairs ot'sheets that are to be collated and written upon. As has been previously stated7 the typewritten matter may liurther be duplicated with the aid of the tally roll mechanism, the tally sheet servi as a register or proof sheet.

lt will be observed that by my present invention there is provided collating mechanism comprising a plurality of paper clamping contrivances, each ot which includes a single clamping jaw and a separate or individual support therefor.r the supports being independent oli each other; that means are provided tor both simultaneously opening and also simultaneously closing the clamping aws in all et the positions in which said 'Zeer conirivances may be set, said means coniprising a finger piece ha or constant normal pofition iter all or the adjusted positions ot the con warmes; that the pair ot contrivances or devices provided in the present instance arer mijns )le along a supporting bar 'forming par Lil p oit a bail which 1s mounted on the platen carriage of proper: and that said last nienl'ioned paper guides together with the clin nps proper are operatively connected with z iid linger piece by trains ot connections which are adjustable automatically wlien the paper clamping contrivances are adiusted: that the iaper guiding or gaging means comp- A adjustable side glides., which the same side edges ot the wort sheets l t are superpoed or to be collated; that two euidcs are provided at the same side ol" i machine, one movable out ot the way olf he other. the latter or outer beine' 'tor the w'. sheetl Vthe movable or inne:I guide bei the narrower sheet; that the movable guide raised or swung` out ol the way ot the other and substantially over the other or outer guide; that the two guides have a co i adjustable support which nuy be a usted to varv the positions olfV the alivelv to the platen; and that means are provided YFor ad justing the said two guides relative :5o each other so as to vary their distance apart.

Various changes may be iliade without departing 'from my in vcntion.
